Fishers are a medium-sized carnivore listed as federally endangered in the southern Sierra Nevada Mountains. Small and isolated populations are the most immediate and challenging threat to fisher persistence. Understanding species distribution and habitat associations are critical information needs for species recovery and conservation. In collaboration with National Park Service partners, we are modeling the distribution and habitat associations of fishers in Yosemite, Sequoia, and Kings Canyon National Parks to assist with ongoing conservation and management efforts. We are developing a hierarchical model of detection-non detection data using occupancy and habitat modeling to estimate the distribution and habitat associations of fisher. We will use these predicted associations to forecast the effects of differing management scenarios and stochastic effects on fishers within the National Parks. Our results will be a useful decision-support tool to promote species recovery in the face of stochastic events and a changing climate.
